Today, more than sixty years later, members of a new generation of scientists are attempting to create life from the ground up. Science has moved forward in leaps and bounds since Schrodinger's time, but our understanding of what does and does not constitute life has only grown more complex. An era that has already seen computer chip-implanted human brains, genetically engineered organisms, genetically modified foods, cloned mammals, and brain-dead humans kept alive by machines is one that demands fresh thinking about the concept of life. While a segment of our national debate remains stubbornly mired in moral quandaries over abortion, euthanasia, and other right to life issues, the science writer Ed Regis demonstrates how science can and does provide us with a detailed understanding of the nature of life. Written in a lively and accessible style, and synthesizing a wide range of contemporary research, What Is Life? is a brief and illuminating contribution to an age-old debate.

    From the emergence of mind, he traces the evolution of human consciousness through its major stages of growth and development. He particularly focuses on modernity and postmodernity: what they mean; how they impact gender issues, psychotherapy, ecological concerns, and various liberation movements; and how the modern and postmodern world conceive of Spirit. This second edition features forty pages of new material, new diagrams, and extensively revised notes.

    Ever since Gilgamesh cut down the ancient cedar forests of Mesopotamia, civilizations and empires have foundered and collapsed in the wake of widespread deforestation. Today, with three quarters of the world's original forests gone and the pace of cutting, clearing, processing, and pulping ever accelerating, Jensen and Draffan lay bare the stark scenario we face--we being not only people, but the nonhuman fabric of life itself--unless deforestation is slowed and stopped. A must read for anyone who wants to understand the relationship between deforestation and our ecological crisis as well as an essential "handbook" for forest and anti-globalization activists.

    Simply put, beliefs come first and explanations for beliefs follow. The brain, Shermer argues, is a belief engine. From sensory data flowing in through the senses, the brain naturally begins to look for and find patterns, and then infuses those patterns with meaning. Our brains connect the dots of our world into meaningful patterns that explain why things happen, and these patterns become beliefs. Once beliefs are formed the brain begins to look for and find confirmatory evidence in support of those beliefs, which accelerates the process of reinforcing them, and round and round the process goes in a positive-feedback loop of belief confirmation. Shermer outlines the numerous cognitive tools our brains engage to reinforce our beliefs as truths.Interlaced with his theory of belief, Shermer provides countless real-world examples of how this process operates, from politics, economics, and religion to conspiracy theories, the supernatural, and the paranormal. Ultimately, he demonstrates why science is the best tool ever devised to determine whether or not a belief matches reality.

    Soon enough, she is happily ensconced in the daily workings of his family. And not only that: Stella is treated like a family member—in ways that dogs of his youth were not. Spending humanlike sums on vet bills, questioning her diet and exercise regimens, contemplating her happiness—how had this all come to pass, when the dogs from Homans’s childhood seemed quite content living mostly out in the yard?In What’s a Dog For?, Homans explores the dog’s complex and prominent place in our world and how it came to be. Evolving from wild animals to working animals to nearly human members of our social fabric, dogs are now the subject of serious scientific studies concerning pet ownership, evolutionary theory, and even cognitive science. From new insights into what makes dogs so appealing to humans to the health benefits associated with owning a dog, Homans investigates why the human-canine relationship has evolved so rapidly—how dogs moved into our families, our homes, and sometimes even our beds in the span of a generation, becoming a $53 billion industry in the United States in the process.As dogs take their place as coddled family members and their numbers balloon to more than seventy-seven million in the United States alone, it’s no surprise that canine culture at large is also undergoing a massive transformation. They are now subject to many of the same questions of rights and ethics as people, and the politics of dogs are more tumultuous and public than ever— with fierce moral battles raging over kill shelters, puppy mills, and breed standards. Incorporating interviews and research from scientists, activists, breeders, and trainers, What’s a Dog For? investigates how dogs have reached this exalted status and why they hold such fascination for us. With one paw in the animal world and one paw in the human world, it turns out they have much to teach us about love, death, and morality—and ultimately, in their closeness and difference, about what it means to be human.
